2 Claims. (Cl. 280-11. 19)

This invention relates to skates of the type which are supported by wheels.

An object of the invention is the provision of a skate having a platform which is supported by wheels of a particular construction so that the skates on the feet of the skater may be directed into close association with the adjacently disposed front wheels for frictionally contact to provide a braking action, the outer surfaces of the wheels being conical so that the surfaces of the inner wheels may come together progressively to retard the speed of the skater without causing an abrupt stop.

A further object of the invention is the provision of a skate which is of simple and durable construction and which is supported by wheels of approximately six inches in diameter with the outer faces of the wheels being in the form of a cone, the conical wheels being of suflicient strength to not only support the weight of the skater but to act as a brake to check the speed when the conical faces of at least a pair of the inner wheels are brought into frictional contact, the shape of the faces providing for an automatically progressive engagement to prevent sudden stops.

The invention is best understood from a consideration of the following detailed description in connection with the accompanying drawings forming part of the specification, nevertheless, it is to be understood that the invention is not confined to the disclosure but is susceptible of such changes and modifications as shall define no material departure from the salient features of the invention as expressed in the appended claims.

In the drawings:

Figure 1 is a side view of my improved skate,

Figure 2 is a plan view of the skate,

Figure 3 is a longitudinal vertical section of the skate,

Figure 4 is a fragmentary plan view of a pair of the skates showing the adjacent front wheels in braking relation,

Figure 5 is a fragmentary plan view of a pair of the skates with the inner adjacent front and rear wheels in braking relation,

Figure 6 is a fragmentary transverse vertical section taken along the line 6-6 of Figure 2,

Figure 7 is an enlarged fragmentary vertical section of the hub portion of a wheel, and

Figure 8 is a view in perspective of a connecting means for a strap.

Referring more particularly to the drawings, Ill designates a platform which is shaped to conform to the sole of a shoe. The platform is made of metal and is provided with a plurality of openings. H to decr ase the weight thereof. A plurality of slots [2 are punched in the platform .to form tongues which are bent to provide bearings l3 for axles l4 and I5.

Front whee s I6, I 6' are mounted on the opposite ends of the axle l4 while rear wheels I1, ll support the opposite ends of the axle [5. Since all of the wheels are of identical construction a descript on of a single wheel and its hub formation will suflioe. Each wheel as illustrated in Figures 6 and 7 consists of an inner flat disk 20 and an outer conical disk 2| joined together in integral formation along the peripheries thereof by a grooved rim 22 which receives a rubber tire 23. A hub section 24 is attached integrally to the central portions of the disks. It will be noted from Figure 7 that the central portion 25 at the outer surface of the disk 2| is flat.

A bearing for the hub 24 includes a roller hearing 30 located between a pair of washers 3| the washer being mounted on a hollow portion 32, at the ends of axles l4 and I5, as clearly shown in Figure 7. A felt washer 33 which is saturated with lubricating oil is disposed between each washer 3| and a relatively thin and stiff washer 34 or 34a. A disk 35 is received by the hollow end of the axle and abuts the inner faces of the washer 34 and the hub portion 24. These disks are welded at 35a to the axles.

A can 33 has an outer conical face 31 and an inner fiat face 38 in contact with the flat portion 25 of the disk 2|. A rod 40 is received by the hollow end of the axle and has its outer end rigid with the inner face 38 of the cap 36. The inner end of the rod is pinned at 4! to the axle.

Straps 45, 46 and 41 are employed for securing the heel portion of the shoe of the skater to the platform Ill while straps 48 and 49 are used to attach the toe portion of the foot of the skater to the forward end of each platform. As shown in Figure 8, a novel form of link 50 is employed for attaching the ends of the straps 45, 4B, 48 and 49 to the skate. The links which are formed of metal have a passage 5| to receive the axles l4 and I5 and a slot 52 to receive a loop at the ends of the various straps.

The wheels are approximately six inches in diameter or are of a size which will prove satisfactory to the skater. As shown in Figures 4 and 5. The facing wheels at the inner sides of the pair of skates may be brought together so that the conical faces of the wheel will move into bearing engagement to effect a braking action. On the other hand, both wheels at the adjacent faces of a pair of skates may be brought together for increasing the braking action.

What I claim:

1. In a skate including a platform, a pair of spaced axles arranged transversely of said platform and supported on the under surface thereof, and a wheel having a tire thereon rotatably supported on each end of each of said axles, the improvement comprising providing the exterior face of each of said wheels with a projection in the form of a cone, said cone extending outwardly of and beyond the outer face of the tire of the adjacent wheel whereby the conical projection of one wheel of one skate of a pair of skates may be brought into bearing engagement with the conical projection on a facing wheel of the other skate of said pair of skates to eifect a bra-king action.

2. In a skate including a platform, a pair of spaced axles arranged transversely of said platform and supported on the under surface thereof, and a wheel having a tire thereon rota'tably supported on each end of each of said axles, the

improvement comprising providing the exterior face of each of said wheels with a projection in the form of a cone, said cone extending outward- 1y of and beyond the outer face of the tire of the adjacent wheel and the apex of said cone lying along the longitudinal axis of the axle on which it is supported, whereby the conical projection of one wheel of one skate of a pair of skates may "be brought into bearing engagement with the conical projection on a facing wheel of the other skate of said pair of skates to effect a braking action.
